Foma still produces DS8mm film some companies offer respooled film: http://www.wittner-kinotechnik.de/ka...m/d8_filmm.php
You can develop the B/W and e6 film at home with the right chemistry, there used to be a spool/tank made for developing 8mm film at home.
Bolex is quiet good but you pay a premium, the Eumig C3 is just as good at a lower price. The Pathé DS8/BTL Double Super 8 is another good choice. 8mm cameras usually have better registration than their Super 8 cousins unfortunately 8mm isn't as available as Super8.

Good luck
